CLEAN AIR INTAKE/COOLING AREAS
To insure proper cooling, make sure the
grass screen, cooling fins, and other
external surfaces of the engine are kept
clean at all times.
Every 100 hours of operation (more often
under extremely dusty, dirty conditions),
remove the blower housing and other
cooling shrouds. Clean the cooling fins
and external surfaces as necessary. Make
sure the cooling shrouds are reinstalled.
NOTE= Operating the engine with a
blocked grass screen, dirty or plugged
cooling fins, and/or cooling shrouds re-
moved will cause engine damage due to
overheating.

or every other oil change if the tractor is

CLEANING
° Clean engine, battery, seat, finish, etc.
of all foreign matter.
o Keep finished surfaces and wheels free
of all gasoline, oil, etc.
• Protect painted surfaces with automo-
tive type wax°
We do not recommend using a garden
hose to clean your tractor unless the elec-
trical system, muffler, air filter and carbu-
retor are covered to keep water out. Water
in engine can result in a shortened engine
life.
